#4----The Phrase "AND WHAT NOT".

This short little diddy makes me cringe.  I have never run into an intelligent person who uses this statement and, unfortunately, those who DO use it usually use it SEVERAL TIMES IN THE SAME SENTENCE. For example:  "So we went to the store and what not, and we bought a bunch of stuff and what not."  This statement is defined by the urban dictionary as:

"A nothing phrase that is used at the start or at the end of a real sentence. . .typically indicating the user is uneducated or on drugs". 

And there you have it, and what not.
